Description

Sealed plug-in connection through a partition and mounting method

The present invention relates to a connector for making at least one electrical connection through an opening of a partition. The connector, which is also referred to as a through-connector, has a first and a second connector which can be plugged together and at least one of the connectors can be sealed against the partition wall via a seal enclosing the opening. In particular, the present invention relates to a connector in which at least one of the plugs has a tensioning device which can be brought into engagement with the other plug and with which the two plugs are permanently tensioned in their mating direction by incorporating the partition wall. The invention further relates to a mounting method for producing such an electrical connector.

In a known generic connector, as shown for example in the published international patent application WO 2004/047234 A1, the tensioning of the two plugs to each other taking into account the partition by means of a sliding device, which for tensioning the two plugs in a direction approximately transversely to Implementing direction is displaced by the partition wall. Guide rails convert the pushing force into a clamping force.

However, in this known tensioning device the problem arises that moisture can penetrate at the connection points between the tensioning device and the plugs, which can lead to failure of the plug connection.

The invention is therefore based on the object to improve a generic connector and a mounting method of the type mentioned in that the tightness against the environment and the reliability of the connection can be increased.

According to the present invention, this object is achieved by a plug connection with the features of patent claim 1. Furthermore, the task by a corresponding assembly method with the steps of the independent method claim solved.

Furthermore, an object of the present invention is to improve a generic plug-in connection and a mounting method of the type mentioned in that in the simplest possible way at least one of the two connectors can be fixed to the partition and assembly errors can be easily detected.

This object is achieved by a plug connection with the features of claim 27 and by a corresponding mounting method with the steps of claim 33.

Advantageous developments of the present invention are the subject of several sub-claims.

The present invention is based on the basic idea that an undesirable penetration of moisture into the interior of the connector can be avoided by sealing the connection region between the clamping device and the at least one connector by means of a sealing device.

According to an advantageous embodiment, the tensioning device has at least one actuating projection, which cooperates for tensioning the plug with a receptacle which is arranged on one of the plugs. In this way can be done in a very simple manner, a translation of the expended during clamping force in a clamping force.

In order to minimize the area which such a sealing device has to seal, the tensioning device can, according to an advantageous embodiment, have a locking lever, which is pivotable about an axis of rotation which runs approximately transversely to the direction of passage through the dividing wall for tensioning the two plugs , In such an arrangement, it is sufficient to seal the area in which the locking lever is rotatably mounted. In order to achieve a particularly effective force transmission of a pivoting movement into a clamping force for tensioning the two plugs, at least one tooth with involute tooth flanks can be arranged on the bearing projections as the actuating projection.

According to an advantageous embodiment, the tensioning device has a locking lever with a base region and two leg regions. At the leg areas bearing projections are formed, which are rotatably mounted in corresponding Lagerausneh- ments of a plug. In this way it can be realized in a particularly simple manner that the locking lever for clamping the connector about an axis of rotation, which extends approximately transversely to the direction of passage through the partition, is pivotable. The sealing device can then be arranged on the bearing projections, for example in the form of an O-ring, or it is alternatively injection-molded directly onto the bearing projections.

A particularly cost-effective and simple realization of the sealing device according to the invention is given when the sealing device is formed by an elastic O-ring.

The seal opposite the dividing wall must be mounted circumferentially around the opening in the dividing wall. According to an advantageous embodiment, the seal can be sprayed onto the outer periphery of the plug, so that the seal is captively attached to the connector housing. In addition, the connection between the seal and the plug on which it is molded, always completely tight. However, this seal can also be a separate part that can be brought into contact with both the plug and the partition.

In order to prevent unintentional release of the tensioning device, a separate securing device, which is also referred to as connector position assurance (CPA), may be provided for locking the tensioning device in a final assembled state. The securing device can be released in a particularly space-saving manner if it is displaceable in a direction transverse to the direction of passage through the dividing wall.

A locking lug, which is provided for locking the tensioning device on the securing device, represents a particularly effective and easily realizable possibility of locking.

As an alternative to the pivotable locking lever, a correspondingly sealed sliding clamping device can also be used, which makes sense, for example, if the available installation space makes it possible to pivot the locking device. rigs lever during assembly does not allow. In this case, the tensioning device may be a sliding device with at least one transmission or reduction arrangement. This allows converting an applied pushing force or movement into a greater or lesser clamping force or movement.

Particularly advantageously, the tensioning device may be a sliding device which is displaceable in a direction approximately transversely to the direction of passage through the partition wall in order to tension the plug. As a result, a particularly simple clamping device on the connector is possible, the clamping can be performed very quickly and easily and the required space can be kept low.

In a further advantageous embodiment of the invention, the tensioning device may comprise at least one guide rail, which extends partially in a plane lengthwise to the mating direction and approximately transversely to the mating direction. This is a sliding force or movement in a clamping force or movement convertible.

If one observes a sealing device at an opening of a first connector housing, through which an engagement element of the clamping device penetrates, then a clamping device designed as a sliding device can be sealed particularly effectively against penetrating moisture. Such a seal can for example be injected and to improve the tightness and more complicated cross-sections, z. B. having at least one sealing lip.

A particularly secure and realized with little effort seal can be achieved if at least one sealing projection is formed on a second connector housing, which cooperates for sealing the connector with the sealing device.

The fact that furthermore a locking device is provided, which is movable between a locked position in which the second connector is fixed to the partition, and an unlocked position, a particularly secure fixation of the second connector can be achieved on the partition. Such a locking device, which can also be referred to as a further connector position assurance (CPA), can be designed so that unlocking is also possible and, in the event of repair, the second connector can be easily removed from the partition wall. On the other hand, if greater forces must be expended when plugging in the first plug, it can be ensured that the second plug is not unintentionally released from the partition wall. In particular, if this second plug is held in a panel plate whose rear side is no longer easily accessible at the time of assembly, as is the case for example in a car door, it can be avoided with the solution according to the invention that the second plug can not be contacted properly.

Characterized in that the locking device is mechanically fixed in the unlocked position, a defined position of the locking device can be ensured in the preassembled state.

Furthermore, at least one latching device can be arranged on the locking device in order to secure the locking device in cooperation with a corresponding latching opening in the locked position. This is particularly important in applications in the automotive sector, because strong mechanical and thermal stresses occur during operation. Thus, the locking device can not move unintentionally from the unlocked position, the at least one locking device in the unlocked position cooperate with another associated locking opening to fix the locking device in this position. Conveniently, this locking connection from the outside (at least for a suitable tool) accessible so that it is solvable in the case of a desired expansion.

The locking device may be displaceable in the simplest case with respect to the second connector in the direction of joining the two connectors. However, this solution has the disadvantage that it can not be ensured that the two plugs are pluggable only when the locking device is properly in its locked position. In order to ensure in a particularly simple manner that the two plugs are pluggable only when the second plug is in its end position in the opening of the partition and the locking device is properly locked, the locking device may be mounted by means of a hinge-like connection to the second connector housing and between the locked and the unlocked position by a pivoting movement about an axis which extends approximately transversely to the direction of passage through the partition to be movable.

In such an embodiment, for example, an edge region lying opposite the axis of rotation in the unlocked state can thus be arranged in the second connector housing such that the two connectors can not be plugged together.

Of course, the proposed in connection with the present clamping device locking device can also be used for other connectors.

The plug connection 100 according to the invention has, in a first embodiment with reference to FIG. 1, a first plug 1 and a second plug 17. In this case, the second plug 17 is mounted in a partition wall 37. According to the present embodiment, the second plug 17 is a male plug and the first plug 1 is the associated female plug, but this is not essential to the present invention since the arrangement of pins and bushings could be reversed.

According to the first connector 1 is sealed by means of a circumferential seal 28 relative to the partition wall 37. As will be explained later with reference to FIGS. 3 and 4, the connector 100 according to the invention has a tensioning device 160 which, in the final mounted position shown in FIG. 1, braces the two plugs against one another, including the partition wall 37. In this case, according to a first embodiment, a locking lever 160 serves as a tensioning device. The first connector 1 has a first connector housing 2, a connecting piece 7 to which a sleeve can be attached, a first pin receptacle 5, and a second pin receptacle 6. The grommet, which is not shown here, and the connecting piece 7 are part a channel through which a cable, not shown, is insertable into the interior of the first connector housing 2. In order to prevent penetration of moisture into the interior of the plug at the connection point between the first plug housing 2 and the locking lever 160, the first plug 1 according to the invention has a sealing device 162. This sealing device is realized in the embodiment shown by a simple O-ring. Of course, however, other possibilities for producing the sealing device can be used, such as molded seals or more complex shaped seals, the z. B. have sealing lips.

As will be further appreciated with reference to FIG. 3, the seal is disposed on a bearing boss 164 which holds the latch lever 160 pivotally in direction 166 in a bearing receptacle 168 of the first plug housing 2. Due to the special shape of the sealing device 162 as an O-ring seal despite the mobility of the locking lever 160 can be ensured in a particularly simple manner.

To illustrate the structure of the locking lever 160, the connector 100 according to the invention is shown in Fig. 2 in a rotated perspective view again. In this view, it can be seen that the locking lever 160 is protected against unintentional unlocking in the direction 166 by a securing device 170. The securing device 170 in this case has a latching lug 172 for latching with the latching opening 174 of the locking lever 160. With this arrangement, on the one hand, it can thus be prevented that the locking lever 160 is pivoted unintentionally and thus the sealing stress between the two plugs 1 and 17 is inadvertently released, but, on the other hand, the latching device 172 remains easily accessible from the outside in order, if necessary, to (at least with a suitable tool) to be able to open.

In Fig. 3, the first embodiment of the connector according to the invention is shown in the unmated state. In this case, the second plug 17 is already mounted in the partition wall 37. An elastic spring arm 152 with a latching nose 131, which are integrally formed on the housing 25, secure the second plug 17 in the opening of the partition 37. During assembly, additional space can be saved, since the second plug 17 in this "parking position" not yet must firmly abut the partition wall 37, but, if necessary, is still slidably mounted. Only when closing the Contact with the first connector 1 and when clamping the contact by means of the locking lever 160, the second connector 17 is attracted to the partition wall 37 and pressed. In this case, the receptacle 176 allows engagement of an integrally formed on the locking lever actuating projection 178 for tensioning the two connectors to the partition wall 37 (see FIG. 4). From the operating principle, the engagement member 176 is formed as a reduced rack, which cooperates with the actuating element 178, which is designed as part of a gear.

In order to prevent the second plug 17 from falling out of the dividing wall during mechanical loading during assembly, a locking device 102 is furthermore provided whose mode of operation is to lock in the locked state a deflection of the latching arm 152 inwards, so that the plug 17 can not fall out of the opening. In the embodiment shown, the resilient latching arm 152 is integrally formed integrally with the plastic housing of the second plug.

As is still clear with reference to FIG. 5, the locking device 102 has a latching lug 110 which, in both the locked and unlocked state, latches in a corresponding latching opening 124 or 126, so that the latching device 102 is captive in both positions is secured. The locking device 102 is between the locked and unlocked positions in the direction 150, i. in Zusammenstecksteckrichtung the two connectors 1 and 17 movable. This is particularly advantageous because the locking device is thus particularly easy to access from the outside and can be easily locked by an operator and also released again. Two elongate cutouts 154 also allow for flexible mobility of the latch 110. An actuating projection 156 facilitates operation of the latch 102 by a user. The surfaces 158 (see FIG. 5) provide in the locked state for the blocking of the latching hooks 131.

A drip protection cap 26 covers the second plug 17 and thus protects against the ingress of dripping water. The first connector 1 is shown here with the locking lever 160 pivoted upwards. The securing device 170, which is displaceably mounted on the housing 2, is located in the illustration shown in a position in which, during the subsequent pivoting of the locking lever 160, latching with the latching lug 172 is made possible. After pivoting the locking lever 160 about the indicated axis of rotation 180, the securing device 170 can be pushed in the direction 182, whereby the locking lug 172 engages with the projection 184 on the locking lever 160 and holds it securely in its locked position. An actuating projection 186 facilitates the displacement of the securing device 170. In order to ensure a secure guidance, the securing device is furthermore held displaceably in corresponding grooves on the housing 2. Finally, a securing tab is formed on the securing device 170, which prevents displacement of the securing device in the direction 182 until it is pressed by the folded-down locking lever 160 to the housing 2 and allows the securing tab 188 is displaceable in the groove 190.

Fig. 4 shows the first embodiment of the first connector 1 in an exploded view. As can be seen from FIG. 4, the first and the second pin receptacle 5, 6 are formed complementary to one another in sections so that the first pin receptacle 5 can be inserted into the second pin receptacle 6 in sections in the direction of the arrow 8. In the assembled state, the first and the second pin receptacle 5, 6 in the direction of arrow 9 in the interior of the first connector housing 2 can be inserted. A latching device 192 ensures a secure hold in the first connector housing 2. According to the invention, the first connector housing has approximately circular bearing recesses 168 through which the bearing projections 164 penetrate and allow rotation about the axis 180 indicated by dashed lines.

According to the invention, an O-ring 162 is pushed over the bearing projections 164 in each case as a sealing device. This O-ring prevents moisture from penetrating through the bearing opening 168 into the interior of the plug housing 2. Opposite the partition wall, the plug housing is sealed in the installed state via the seal 28. This seal can be either molded or as a prefabricated part, for example made of silicone rubber, manufactured and mounted on the connector housing 2. The lock Lever 160 has a substantially U-shaped configuration with two legs, on which the bearing projections 164 are formed, and a base, which engages with the securing device 170 on. Due to the fact that the locking lever 160 partially surrounds the housing 2, the most space-saving possible arrangement can be realized.

On the bearing projection 164, a part of a gear wheel is in each case formed as an actuating element 178, which engages with corresponding engagement elements 176 on the second connector housing 25. Advantageously, the actuating element 178 is formed as part of an involute toothing and the tooth flank 194, which must hold the entire force in the final assembled state, is integrally formed on the solid material of the bearing projection 164 in order to allow better power and long-term stability.

The second plug 17 of the connector according to the invention according to the first embodiment is shown in Fig. 5 partially exploded. The second plug 17 has a second plug housing 25, a drip protection cap 26 and a locking device 102.

The drip protection cap 26 can be pushed onto the second connector housing 25 in the direction of the arrow 29. In this case, an outer periphery 30 of the second connector housing 25 and a Umgreifrand 31 of the drip protection cap 26 engage each other.

In the assembled state, the drip protection cap is secured to the connector housing 25 via a catch 196.

As can be seen from the illustration of FIG. 5, the locking device 102 has an actuating projection 156, which facilitates the operation of the locking device by the user. The surfaces 158 provide in the locked state for blocking the latching hooks 131st

Finally, FIG. 6 shows the second plug 17 again in the plug-in position held in the partition 37. The function of the illustrated in Figures 1 to 6 first embodiment of the connector of the associated assembly method will be described below.

First, the first connector 1 is pre-assembled. Referring to FIG. 4, the first pin receptacle 5 is inserted in the arrow direction 8 in sections into the second pin receptacle 6. In this state, the first and second pin receiving 6, 5 are inserted in the direction of arrow 9 in the interior of the first connector housing 2. Thereafter, a spout (not shown here) can be pushed over the connecting piece 7 in sections. For mounting the first connector 1 further includes mounting pins in the first and second pin recordings and laying a Zuführkabels through the interior of the spout in the interior of the first connector housing 2 and connecting wires of the connecting cable with corresponding pins.

Regardless of the assembly of the second plug 17 is carried out. In particular, the drip protection cap 26 is pushed onto the second connector housing 25 in the direction of arrow 29. Also in the second connector 17 pins are used and one or more feed lines are placed.

Now, the connection can be made through the opening 39 of the partition wall 37 by means of the connector according to the invention. In this case, the connection in this embodiment is an electrical connection.

With reference to FIGS. 5 and 6, the second plug 17 is guided in the direction of the arrow 38 through the opening 39 of the dividing wall 37. The execution takes place until the locking projections 131 are secured to the partition wall. Subsequently, the locking device 102 is inserted in the direction of 103 in the housing 25 and pushed down until a latching takes place in the latching opening 124 and is therefore secured over the surfaces 158 of the latching arm 152 against bending inwards, so that the second plug 17th now captive secured in the partition.

The second plug 17 is now secured in its position relative to the partition wall 37. This can be a pre-assembly state in the automotive industry. Now the mating of the first and second plug 1, 17 can take place. Starting from the position of the first and second plugs 1, 17 shown in FIG. 3, the first plug 1 is brought to the second plug 17 in the direction of arrow 150 and plugged together with the second plug 17.

Then, a force is applied to the actuating surface 11 of the locking lever 116, so that the locking lever 116 is pivoted about the axis 180 and thereby the applied force by means of the gear / rack assembly 178, 176 translated into a tensioning movement. As a result, voltage is built up until the actuation element 178 has assumed its end position in the engagement element 176. Furthermore, the latching hook 172 engages with the latching opening 174. In the next step, the securing device 170 is displaced in the direction 182 (see FIG. 3), whereby the latching hook 172 is secured to the projection 184 and the tensioning device is held against unintentional movement from the now assumed end position. Due to the mechanical stress, the seal 28 is pressed against the partition wall 37, so that in this position together with the seal of the locking lever 160, the first plug 1 is securely protected against moisture penetration.

A second advantageous embodiment of the connector according to the invention will now be explained with reference to Figures 7 to 16.

As can be seen from FIG. 7, according to a second embodiment, instead of the tensioning device designed as a locking lever, the first connector 1 has a sliding device 704 for tensioning the two connectors against one another. The pusher 704 is slidably received in the direction of arrow 10 in the first connector housing 2. The pusher 704 has an actuating surface 11 to which a displacement force for displacing the pusher can be applied.

The pusher 704 has side members 12, 13. As shown in FIG. 7, upper guide rails 14 and lower guide rails are respectively provided in side elements 12, 13. ment rails 15 provided. The guide rails 14, 15 are guide recesses in this embodiment of the invention.

In FIG. 7, an intended mating direction of the first plug 2 to the second plug 17 is further indicated by an arrow 16. The direction 10, in which the sliding device 704 is displaceable in the first connector housing 2, extends approximately transversely to the mating direction 16 of the first connector 1 with the second connector 17 ^" . The guide rails 14, 15 have reduction sections 18, 19 which are in one Direction approximately transverse to the mating direction 16 and approximately transverse to the sliding direction 10. In addition, the guide rails 14, 15 end portions 20, 21 which extend parallel to the sliding direction 10.

As can be seen with reference to Fig. 8, the guide rails 14, 15 cooperate with associated pin-like projections 33, 34 for clamping the two connectors against each other and to the partition wall.

According to the invention, corresponding to the pin-like projections 33, 34 openings 72, 73, through which the pin-like projections 33, 34 penetrate to cooperate with the sliding device 704, provided with circumferential seals 163 to this connection area against ingress of moisture into the plug inside seal.

On the first connector housing 2, a seal 28 is further circumferentially mounted. In the embodiment of the present invention shown in FIG. 7, the seal 28 is sprayed onto the housing 2. The seal 28 is thus captively secured to the first connector housing 2, and the connection between the seal 28 and the first connector housing 2 is always sealed. However, the seal 28 may also be a separate part to the first connector housing 2.

The above also applies to the seals 163, which are also molded onto the first connector housing of the embodiment shown. In Fig. 8, the second connector 17 according to the second embodiment is shown in partially exploded view. Those elements which correspond to those according to the first embodiment are not mentioned separately again in the following.

According to the invention, the second plug 17 in the second embodiment, pin-like projections 33, 34 which are integrally formed on the plug housing 25. The pin-like projections 33, 34 are formed so that they can be engaged with the guide rails 14, 15 of the slider 704 of the first connector and thus constitute engagement means for the tensioning device 704 serving as a tensioning device.

For sealing the openings 72, 73 by means of the seals 163 sealing projections 198 are further integrally formed on the second connector housing 25, which can form a sealing connection with the seals 163.

An elastic spring arm 152 with a holding device 131 serves, as will be clear with reference to FIG. 10, an attachment of the second plug 17 in the opening of the dividing wall 37. A locking device 102 permits blocking of this elastic spring arm 152 for locking the second plug 17 in FIG the partition by an inward bending of the spring arm 152 is verhin in the locked state.

In this case, the locking device 102 according to this second embodiment, as will become more apparent with reference to Figures 1 5 and 16, bearing projections 206, which are held in corresponding bearing recesses 208 on the second connector housing 25. Thereby, the locking device 102 can be moved between a locked and an unlocked position about a rotation axis 202. In the unlocked position, the locking device 102 is secured in the latching recess 210, in the latched position in the latching recess 212.

FIG. 9 shows a perspective view of the plug-in first plug 1.

In Fig. 10 the plug-ready second connector 17 is shown, wherein the locking device 102 is in the locked position, so that the second plug 17 in the Partition 37 is securely held. In this position, moreover, the edge 204 of the locking device 102 with the connector housing 25 in such a system that the pin tray released and thus plugging together the two connectors is possible.

11 shows a perspective, partially cutaway view of the connector according to the invention according to the second embodiment in the final assembled and assembled state. According to the invention, the sealing devices 28 and 163 ensure a complete sealing of the internal electrical connections against the ingress of moisture. The two plugs 1 and 17 are firmly clamped to the partition wall 37.

With reference to FIGS. 12 and 13, the assembly of the second plug 17 in the partition wall 37 according to the second embodiment will be explained in more detail below. In contrast to the previous embodiments, a seal 27 which is analogous to the seal 28 is provided on the second connector 17 for sealing against the partition wall 37. However, it is clear to the person skilled in the art that it is irrelevant for the principles according to the invention on which side of the partition wall 37 a seal is provided.

It is, as seen in the partially opened view of FIG. 12, the locking device 102 in the unlocked position. For mounting, the second plug 17 is hung obliquely into the opening of the partition wall 37, wherein the provided free distance 134 ensures that the required tilting by the angle is possible.

After hanging, the second plug 17 is pivoted about the lower edge in the direction 112, so that the projection 131 holds the second plug 17 in the partition wall 37.
